<p><P>PROBLEM TO BE SOLVED: To suppress deterioration in receiving precision, when a known signal for estimating a path for transmission is transmitted. <P>SOLUTION: A control section 30 generates a packet signal formed of a plurality of sequences, while cooperating with an IF section 26, a modulation/demodulation section 24, and a baseband processing section 22. With reference to a known signal arranged in one of sequences where a data signal is arranged, the control section 30 performs timing shift for an extra known signal, arranged in a sequence with data not being arranged, while performing cyclic timing shift of a known signal, arranged in other sequences within the known signal. The timing shift amount is previously provided with priority, and the control section 30 uses the timing shift amounts sequentially, starting from that having high priority for the sequences where the data signal is arranged, and also uses the timing shift amounts, sequentially starting from that having high priority, even for the sequences where the data signal is not arranged. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
